That's what I do, but the signal says childAdded, where model needs
childWillBeAdded and childHasBeenAdded to handle beginInsertRows/endInsertRows,

since beforeRemoveRows triggers accesses to the to-be-removed rows you can run
into serious issues if the child has been delete'd
If I recall correctly, you would respond to childAdded by first calling
childWillBeAdded, doing the work of adding the child, then calling
childHasBeenAdded. The WillBe and HasBeen functions are used to inform the base
class of what your code is doing.
But when childAdded is called… child already has been added. That's the
issue, model is not manipulating data, it's just supposed to react on
their changes
